Excessive and dangerous delay in throttle response due to auto start/stop system causing vehicle to coast when slowing down at a yield sign or intersection etc before transmission re-engages. the vehicle is powerless for several seconds despite application of gas pedal, causing oncoming traffic to potential collide with "stalled" q8. this is a major design defect in the auto start/stop system and occurs every time the system is active.
Start/stop system has nearly caused two major accidents for me. turning left at an intersection with approaching traffic and plenty of time under normal circumstances to proceed......push accelerator and 2 to 3 second hesitation (turbo lag). car does not move. there is no way to permanently disable this defective system in the audi q8.
There is a noticeable throttle lag (hesitation) when the auto start/stop feature is enabled, and the car comes out of a rolling stop (ex. when making a left turn). disabling the auto start/stop feature or selecting sport mode negates the issue.
